摘要

A method for the precipitation of uranium, heavy metals and toxic metals from carbonate - / hydrogen carbonate hold strength by weight water, especially by means of natural uranium and its natural decomposition products, radioactively contaminated waters, which before the precipitation of the uranium calcium hydroxide is added, characterized in that, before the calcium hydroxide addition by the addition of acid and intensive mixing with acid to a ph - value of less 4,3, an extensive destruction of the uranium carbonate complex, and in the destruction of the uranium carbonate complex, as well as the leading carbonate destruction and formed in the waters dissolved carbon dioxide from the water to be cleaned by appropriate selection and suitable measures, with the highest available natural water temperature the be fed to the process, substantially completely by blowing in a finely divided by means of suitable aeration air is expelled.
